• Cable glands, adapters and/or blanking elements shall be installed so as to maintain the
specified degree of protection (IP Code) of the equipment.
• The antenna and the surge arrester shall be simple apparatus in accordance with EN
60079-14. Li and Ci of the simple apparatus shall be negligible. Temperature class of them
shall be determined from Po = 100 mW for ISA and Po = 130 mW for WLAN1/WLAN2.
• The following conditions must be met for the connections to ISA, WLAN1, and WLAN2.
(total Li of simple apparatuses) + (total Lc) ≤ 0.5 mH
(total Ci of simple apparatuses) + (total Cc) ≤ 0.09 μF
• The equipment shall be earthed in accordance with EN 60079-14, in order to maintain in
-
trinsic safety. A cable lug or a similar device shall be used to maintain the secureness of the
connection to the equipment. Care should be taken to avoid multi-point earthing since the
equipment is not galvanically isolated from the power supply.
